I personally think that the closest you will get to "complete, final and perfect" Biblical texts would be to read them in the original Greek and Hebrew. Anything else is a translation...yes, even KJV. This is a circle argument, though, because KJV-onlyists will never admit that God can speak through other translations and that they are valid and trustworthy and those that believe that other translations are great, especially studying side by side will never conform to the 'only KJV' mentality. Around and around the mulberry bush we go, chasing the weasel and getting nowhere.
I firmly believe that these are the kinds of things that turns some away from Christianity. Why are we arguing about this when polygamy has been legalized in Utah, same-sex marriage is being approved everywhere, overriding the voice of the people, and that abortion is running rampant...not to mention all the planks in our own eyes. Do we really believe God is going to judge our lives based on the translation of the Bible we read? Or, are we to be judged based on the love we show and the lives we lead?
I said it before, God is more powerful than man and translations. He will speak. The hungry will hear and obey. That is what matters.
